WASHINGTON (Reuters) – President Barack Obama expanded his lead over Republican challenger Mitt Romney to 6 percentage points in the White House race this month as voters became slightly more optimistic about the economy, a Reuters/Ipsos poll showed on Tuesday.

WASHINGTON (Reuters) – Prominent U.S. Democrats conceded on Tuesday they could have done a better job of selling President Barack Obama’s healthcare overhaul to the public, but said the law could still be an effective campaign issue even if it is struck down by the Supreme Court.

Two days before the high court rules on the law’s constitutionality, congressional Democrats told the Reuters Washington Summit they hoped to put Republicans on the defensive during the campaign for opposing the law’s more popular elements.

LAKE BUENA VISTA, Florida (Reuters) – Republican presidential candidate Mitt Romney tried to make up ground with Hispanic voters on Thursday, promising a long-term solution to allow young illegal immigrants to stay in the United States, but offering just a few minor immigration proposals.

PROVIDENCE, Rhode Island (Reuters) – After a gut punch in Wisconsin and frequent bouts of disappointment with President Barack Obama, liberal activists could be excused for a lack of enthusiasm about November’s U.S. election.

But many of those attending Netroots Nation, a three-day gathering of grassroots progressives in Rhode Island, said the stark choices in the looming battle for control of the White House and Congress were all the motivation they need.

WASHINGTON (Reuters) – Republican Wisconsin Governor Scott Walker’s recall victory raised numerous warning flags for President Barack Obama and his fellow Democrats, who badly flunked the first big political test of the 2012 campaign.

Walker’s surprisingly easy win over Democrat Tom Barrett on Tuesday was fueled by a big turnout from a motivated Republican base of voters, and by heavy spending by out-of-state conservatives who flooded Wisconsin with campaign cash.
