National Republicans may have abandoned Mark Sanford, but Sen. Lindsey Graham (R-S.C.) took to Twitter Wednesday morning to vouch for the former governor.

Graham dispatched four tweets from his campaign Twitter account Wednesday ahead of next week's 1st district special election, including one encouraging voters not to sit on the sidelines.

Graham donated to Sanford's campaign after he won the GOP nomination, but has been quiet about the race since word surfaced that Sanford's ex-wife had accused the former governor of trespassing on her property.

Sanford needs all the help he can get as Democrat Elizabeth Colbert Busch has seized the high ground leading up to Election Day. Colbert Busch outraised Sanford by a wide margin in the most recent period, and her national Democratic allies have been pummeling him over the airwaves.

Sen. Rand Paul (R-Ky.) and his father former congressman Ron Paul, have endorsed Sanford in the last few days. And Gov. Nikki Haley (R) is going to help Sanford raise money on Wednesday.
