Generally speaking, even the bars on K Street lower their prices for happy hour as a lure for the work-weary to kick back a few and ease the stress of a long day.

So charging $1,000 for drinks might seem a bit steep, even for power drinkers enjoying bottles off the top shelf.

The e-mail, obtained by The Hill, said the Clintons’ Georgetown home on Whitehaven Street has “a handful of slots available” for those willing to pony up $1,000 to drink with the former president from 5 to 6:30 Wednesday evening.

The catch, other than the cost and possible liver damage, is that only those who still have money available to be used for the primaries are invited. In other words, the legions of Clinton contributors who have already maxed out will have to rely on their flasks and are not welcome Wednesday for drinks with Bill Clinton.

The invitation to primary contributors speaks loudly to the mad dash for cash the Clintons are engaged in with rival Sen. Barack Obama (Ill.) as the primary battle now looks to go even deeper into the states.

Obama continues to shatter just about every fundraising record on the books, including those only recently recorded. Obama is reportedly raising about $1 million a day, including more than $30 million in January alone and $7.5 million in the less than 48 hours after Super Tuesday.

The Clinton campaign, on the other hand, faced questions after reports that Clinton had loaned her campaign $5 million before Super Tuesday. That news coalesced with reports that some senior staffers, including then-campaign manager Patti Solis Doyle, were going without pay. Solis Doyle has since stepped aside and was replaced by longtime Clinton confidante Maggie Williams.

The Clinton campaign said Tuesday afternoon that this week’s fundraiser is no different from many they have had previously at Whitehaven.

The campaign insists that it is on solid financial footing, and notes that it has raised more than $10 million online since Feb. 5.

Still, the fight with Obama is proving to be both long and expensive.

Campaign chairman Terry McAuliffe revealed on a conference call with supporters recently that Bill Clinton is being dispatched to raise money in Texas, New York and California.

Much of the funds are going toward ads. McAuliffe said the campaign was buying ads in Washington state, Maine and Nebraska, three states Obama swept over the weekend. In addition to those purchases, McAuliffe said the campaign plans to buy ads in Clinton’s firewall states of Ohio and Texas, which hold their primaries on March 4.

Clinton’s campaign announced it is also advertising in Wisconsin, which holds its primary next Tuesday.

However, in the wake of a weekend filled with wall-to-wall losses for the Clinton campaign, The New York Times reported Tuesday that Clinton has been working to “reassure nervous donors” who think Obama might be on the verge of running away with the nomination.

Reports began to surface this week that one of the reasons the Clinton campaign didn’t campaign more aggressively in caucus states is because of a cash crunch that Clinton was only made aware of after her loss in the Iowa caucuses.

The race for delegates is far from over, and as such, the race for cash will no doubt find yet another gear.

With relatively expensive media markets awaiting the candidates in Ohio, Texas and Pennsylvania, the candidates have plenty of opportunities to spend it before this summer’s convention.
