With less than three weeks to go before votes are cast, it's crunch time for any big names who hope to get on the ground floor of the next administration. It's also time to roll out endorsements that have been in the works for weeks, in hopes of winning a few new votes late in the game.

Hillary Clinton, whose campaign has been based largely on inevitability, is benefiting from more establishment Democratic endorsements than we could report this week: Iowa Congressman Leonard Boswell. Oregon Governor Ted Kulongoski. Now, Maine Governor John Baldacci joins the campaign, they announced this morning.

On the GOP side, Mitt Romney keeps piling up conservative backing. While many have questioned Romney's own dedication to conservatism, he's won support from pro-life lawyer James Bopp Jr., ACU chief David Keene and Bob Jones III, all three of whom lend Romney their own conservative credentials.

This morning, Romney is getting a big boost that should help him among hard-core conservatives as he fights to get to the top of the GOP pack. Romney's team this morning announced support from Judge Robert Bork, whose Supreme Court nomination was derailed in 1987 but who remains one of the best-known and most highly regarded conservative jurists in the country.

The nods speak to both campaigns' emphasis going into the final stretch: Clinton, looking for support in what could be a longer than expected Democratic race, emphasizes her establishment credentials in Democratic circles around the country. Romney, not trusted by some in the conservative base, emphasizes his right-leaning credentials by associating with the biggest names in the movement.
