Idahoans cast their ballots in a crucial House primary, Sen. Barbara Boxer (D-Calif.) releases her fundraising numbers ahead of President Barack Obama's swing through San Francisco and Illinois Senate candidate Alexi Giannoulias (D) doesn't have Democratic support locked up.

Ward's day of reckoning

Rep. Walt Minnick and the Democratic Congressional Campaign Committee will be eagerly watching the returns Tuesday night from Idaho's 1st district primary. The freshman Democrat is a top target for the GOP after squeaking past Republican Bill Sali by some 4,000 votes in 2008. Republicans were initially excited by Marine veteran Vaughn Ward, but a series of missteps and revelations — he briefly worked for a Democratic legislator — has left strategists scratching their heads.

Ward also received some high-profile endorsements, including one from Sarah Palin, but he's facing stiff competition from state Rep. Raul Labrador (R).

Meanwhile, Minnick has the backing of the Tea Party Express.

Don't ask how much this trip raised

Obama travels to San Francisco this evening, where he'll headline two fundraisers for Boxer and the Democratic Senatorial Campaign Committee at the Fairmont Hotel and one at a private residence, according to the White House.

The San Francisco Chronicle expects the event will help Boxer raise $1.5 million for her reelection bid.

Ahead of Obama's trip, the Boxer camp announced she'd raised $2 million from April 1-May 19 and now has $9.6 million cash on hand.

Obama's previous visits to San Francisco drew protests, but with reports that "Don't ask, don't tell" is about to be repealed, he could be greeted as a liberator.

Losing friends and alienating people?

Reports that Rep. Jesse Jackson Jr. (D-Ill.) will remain neutral in the Illinois Senate race raise questions about Giannoulias's level of support among the state's top Democrats. Jackson cited his friendship with GOP Senate candidate Rep. Mark Kirk as the reason for his reticence, but he's not the only one thought to be waffling.

Giannoulias's run for state treasurer in 2006 reportedly angered state House Speaker Michael Madigan (D), who was backing the slated Democratic candidate whom Giannoulias defeated. In a sign that things may not be all sqaure, Madigan recently joked to reporters about the Giannoulias's banking woes.
