Upon President Barack Obama's visit to San Francisco Thursday evening, the Republican National Committee (RNC) is reminding people of a controversial remark he made there last year.

At an April 2008 fundraising event in San Francisco, then-candidate Obama raised the ire of many, saying that small town Americans are bitter because "they cling to guns or religion or antipathy to people who aren't like them or anti-immigrant sentiment or anti-trade sentiment as a way to explain their frustrations."

Obama later said he used the wrong words to describe their mood, but the RNC did not miss out on their opportunity to bring up the president's comment. Their research team tweeted:

Meanwhile, Obama heads to San Fran for fundraiser. Remember his last San Fran trip? Or are you still bitter... http://is.gd/4l7ne

In the linked blog post, the RNC provides a quote of Obama's remark. The president is traveling to San Francisco to speak at a Democratic National Committee fundraising dinner.

The RNC made the tweet using the new @RNCResearch account, created in conjunction with the launch of their new website.

Obama is spending the first portion of the day in New Orleans.
