Meantime, Democrats remain bitterly divided after their brutal primary fight. So much so that the loser, Lt. Gov. Dan Mongiardo (who lost by 3,592 votes), had initially planned to ask for a recanvassing of all voting machines and absentee ballots across the state. The winner, Attorney General Jack Conway, a down-the-line liberal ideologue, definitely does not fit the state's center-right profile. He supported the massive health care bill and backed labor's card check bill to unionize businesses without a secret ballot. The far-left DailyKos website calls him "courageously progressive for his state."

But Paul is popular in the state where Obamacare is intensely opposed by 60 percent of the voters who want it repealed, and is the odds-on favorite to win this open seat.

ARKANSAS: The Democrats' worst nightmare turned into a reality Tuesday when unpopular Democratic Sen. Blanche Lincoln could not win her primary and was forced into a June 8 runoff against liberal Lt. Gov. Bill Halter after receiving well below the 50 percent she needed for renomination.

It means the Democrats' costly and deeply divisive primary fight will continue to embroil their party for weeks, while Republican Rep. John Boozman, who won in an eight-way primary, is rebuilding his campaign war chest and preparing for the general election.

Both Lincoln and Halter, whose campaign was bankrolled by the AFL-CIO, are far too left wing for this red state's electorate, where a majority of voters, including a large population of seniors, is fiercely opposed to Obama's health care plan that both support.

A Talking Points Memo poll average shows Boozman leading Lincoln by a margin of 54.2 to 37 percentage points and Halter by a similar margin.

This was not a good week for Democrats on other Senate fronts, either.

Republicans had virtually written off any chance of picking up the open Senate seat in Connecticut being vacated by Sen. Chris Dodd. That is, until a blockbuster front-page article in the New York Times revealed that state Attorney General Richard Blumenthal had lied about serving in the military in Vietnam when he had never been in the war.

Suddenly, there were calls for the Democratic frontrunner to drop out of the race. The Cook Political Report said he is no longer the heavy favorite and rated the race a tossup, and Republicans now had a real shot at another Democratic pickup to add to their list.

And that list of endangered Democratic Senate seats is growing. Three of them: Illinois, Indiana and Nevada, are leaning Republican. Delaware and Arkansas are likely Republican pickups. And three more -- California, Colorado and Pennsylvania -- are tossups.

Right now, Senate Democratic Leader Harry Reid -- who looks like he will be one of his party's casualties -- has a 59-seat majority. After November, the Democrats will be lucky to have 51.
