President Barack Obama is making a down payment on his vow to go all in for Democrats in 2014, courting well-heeled donors in California on a two-day fundraising jaunt that requires him to walk a fine line: If he berates Republicans too much he could jeopardize achieving his second-term goals. 

Obama's California swing, which started with two fundraisers for House Democrats, kicks off a concerted effort to help his party win back the House and keep its Senate majority next year. It's a mission that, if successful, would improve his playing field and help him secure his legacy during his final two years in office.
