A House Republican on Tuesday welcomed debate in his reelection bid as internal sparring ramped up yet again within the GOP ranks.

Rep. Bob Inglis (R-S.C.) took to his campaign Twitter account to welcome debate with his opponents -- saying that he is not going to shy away from disagreements like other incumbents:

Incumbents typically run from debates. I run to them! Debates are crucial for vetting candidates and ideas. Ready or not, let's debate!

Grassroots conservatives have criticized the Republican Party establishment for backing candidates they deem too liberal in several primary races around the country.

The resignation on Tuesday of Florida Republican Party Chairman Jim Greer again highlighted the rift. Greer favored Gov. Charlie Crist (R) in the state's open-seat Senate primary but many grassroots conservatives favor former Florida House Speaker Marco Rubio (R) and have attacked Crist and his national GOP supporters.

"I determined that the party should always come first," Greer said after stepping down. "These distractions and these attacks on each other within the party are not what we should be doing."

Inglis did not comment specifically on any races.

National Republican Senatorial Committee Chairman John Cornyn (R-Texas) has expressed similar sentiments. Cornyn has frequently said he welcomes open primaries amid criticism that his group is shutting out more conservative candidates.

Inglis' race has not received such scrutiny nationally.

The South Carolina congressman faces greater than six Republican primary challengers as well as two Democratic opponents.

Inglis has not shied away from criticizing fellow Republicans. In September he called on fellow South Carolinian Rep. Joe Wilson (R) to apologize on the House floor after shouting "you lie!" at the president during his joint address to Congress.

Most Republicans backed Wilson and decried calls to apologize.
