Marco Rubio, the freshman Senator from Florida is the hope of the Republican Party to reach out to the country’s Hispanic voter. However, a debate on any reform of immigration could cause that bloc of voters to become alienated. Groups against illegal immigration say the bill crafted by Rubio could be a vehicle for proposals like legislation that would require employers to confirm the immigration status of its workers and revoking automatic citizenship through birthrights.

Votes on proposals that are controversial such as these could hurt Republicans candidates with the Hispanic vote, but could also rally the base of the GOP, which is pushing the government to help with more to combat the flow of illegal immigration.

Rubio is nearing the unveiling of his plan for allowing illegal immigrants who arrived in the U.S. as young children to stay if they fall under certain criteria. The Rubio legislation could serve as one alternative to the DREAM Act of the Democrats, which grants a road to citizenship to those illegal immigrants who arrived in the U.S. as young children.

Rubio said all he is awaiting are figures from the Budget Office about the cost of the bill and how many illegal immigrants would be affected by his legislation. He said he was confident that a number of Democrats would support and vote for his bill.

Luis Gutierrez a House member from Illinois and a leading Democratic advocate for immigration reform said in May that up to 95% of Democrats might support the legislation of Rubio if it stops deportations and was reasonable and sensible. A small group of conservatives in the Republican Party could force their colleagues to vote on ending citizenship through birthright.
