Mitt Romney may have clinched the Republican nomination this week, but most voters aren't happy with the choices they now face in this year’s presidential election.

Just 19% of Likely U.S. Voters believe Romney and President Obama are the two best people running for the presidency. A new Rasmussen Reports national telephone survey finds that 64% don’t believe they're the best possible nominees. Seventeen percent (17%) are undecided.
