Oppose Lynch, and they’ll be ignoring a sparkling performance at a Senate hearing last month that won good reviews from members of both parties, who agreed she was qualified to lead the Department of Justice.

The “no” votes will also feed into Democratic arguments that the GOP is needlessly blocking confirmation of the first black woman to be attorney general, something that will be used against the Republican Party in 2016, when it seeks to defend 24 Senate seats.

If confirmed, Lynch would replace Eric Holder, the attorney general despised by most Republicans.

The problem is immigration and Lynch’s comments that Obama’s executive actions shielding millions from deportation were probably legal.

That’s raised the ire of two presumptive GOP presidential candidates, Sens. Ted Cruz (Texas) and Rand Paul (Ky.), who are both loudly opposing her nomination — something that could make it difficult for many Republicans to back her.
