A new poll put out by Kellyanne Conway suggests that Americans do not want the president to go it alone on immigration. According to this poll, only 21% of Americans would prefer President Obama to act alone on immigration. Even 56% of Democrats do not want the president to change immigration policy unilaterally.
Contrary to the White House and the Gang of Eight, 75% of Americans think that employers in need of workers should raise their wages and improve working conditions in order to attract workers; only 8% say that these employers should be able to bring in foreign workers to fill job openings. Americans of all types agree that the government should work to protect the interests of American workers.
