			 Concern about the strength of the U.S. economy, coupled with 
			worries about Ebola and Islamic State militants, are driving the 
			dour mood of a restive electorate. Democrats could pay the price 
			when voters elect 36 senators, all 435 members of the House of 
			Representatives and 36 state governors. 
 Obama's name is not on the ballot, but his low job approval rating 
			reflects a lack of confidence in his leadership during the sixth 
			year of his presidency. Polls indicate Democrats have less 
			enthusiasm for voting than Republicans, and history shows the party 
			that is in power in the White House in midterm elections usually 
			loses seats.
 
 "There doesn't seem to be a lot of things for people to feel good 
			about," said David Yepsen, director of the Paul Simon Public Policy 
			Institute at Southern Illinois University. "It may not be fair, but 
			they tend to take those kinds of feelings out on the White House, 
			and as a practical matter I think the Senate goes Republican."
 
 In the House of Representatives, Republicans are expected to build 
			on their majority of 233 seats to 199 for Democrats. They also will 
			likely retain their majority in the number of governors' seats they 
			hold in state capitals.
 
 
			 
			But the heavy campaign action has been in the 100-member Senate, 
			where Republicans need to pick up six seats to reclaim the majority 
			from Democrats and control both chambers of Congress for the first 
			time since the 2006 election. While Republicans are expected to gain 
			seats, as many as eight to 10 Senate races are still considered 
			toss-ups that could go either way.
 
 There is a good chance the party that controls the Senate will not 
			be known on Tuesday night. Senate races with multiple candidates in 
			Louisiana and Georgia, where the winner must get more than 50 
			percent of the vote, could be forced into runoffs in December or 
			January, respectively.
 
 If Republicans do take control of the Senate, Obama's last two years 
			in office would be complicated by the prospect of even more partisan 
			gridlock, although it could force him to make more compromises with 
			his political opponents.
 
 A Republican-led Senate would be likely to push ahead with approval 
			of the Keystone XL crude oil pipeline, chip away at provisions in 
			Obama's signature healthcare law, and take steps toward a broad 
			rewrite of tax laws.
 
 According to a Reuters-Ipsos poll in late October, just 38 percent 
			of Americans approve of Obama's handling of his job as president, 
			compared to 56 percent who disapprove. Meanwhile, just 24 percent 
			think the country is headed in the right direction, and 61 percent 
			believe it is on the wrong track.
 
 About 58 percent of Republicans are dead certain they will vote, 
			compared to 44 percent of Democrats, the Ipsos poll shows.
 
 POLITICALLY RADIOACTIVE
 
 Obama's unpopularity has made him politically radioactive on the 
			campaign trail. Democratic candidates have kept him at arm's length 
			in competitive states where Senate control will be determined.
 
 Instead, he has largely been restricted to Democratic fund-raising 
			events, although in recent days he headlined events in friendly 
			states such as Maine, Rhode Island and Michigan. On Sunday, he 
			travels to Connecticut and Pennsylvania.

			"I'm not on the ballot this time and this is the last election cycle 
			in which I'm involved as president," said Obama, who was elected to 
			the U.S. Senate in 2004, and to the White House in 2008 and 2012. 
			"Look, it makes you a little wistful, because I do like campaigning. 
			It’s fun," he said in Portland, Maine, on Thursday night.
 Although the White House publicly predicts Democrats will hold on to 
			the Senate majority, people who have visited the West Wing recently 
			say a grim mood has settled in.
 
 But Democrats said the number of close races still gives them a shot 
			to hold the Senate, particularly if their vaunted, data-driven voter 
			turnout operation tips some key races in their favor.
 
 "The Republicans have done a good job of making the president and 
			his agenda the issue. The only way Democrats are gong to win in the 
			end is if they remind voters that all politics are local," said 
			Democratic strategist Jim Manley.
 
 The Republican drive to a Senate majority is focused on defeating 
			Democratic incumbents in what polls show are tight races in 
			Louisiana, Arkansas, Alaska, North Carolina, New Hampshire and 
			Colorado, and winning a fierce battle for the open Iowa seat of 
			retiring Democrat Tom Harkin.
 
 Democrats are trying to make the task harder for Republicans by 
			beating Senate Republican leader Mitch McConnell in Kentucky - he 
			has a small but consistent lead in recent polls - and winning the 
			Georgia Senate seat being vacated by retiring Republican Saxby 
			Chambliss.
 
 Republicans who began the year campaigning against the rocky rollout 
			of Obama's healthcare law have ended it by emphasizing what they 
			call Obama's failed leadership.
 
			  
			
			 
			
 "The president wanted to frame this election around this battle 
			about which party was better positioned to represent middle-class 
			voters," said Republican strategist Kevin Madden. "What's happened 
			instead is we've seen the country lurch from crisis to crisis and as 
			a result the public’s confidence in the president and Washington as 
			an institution has eroded."
