Mitch McConnell has led the Senate Republicans for nearly 20 years, but his time in power may be running out.

Speaking exclusively to The Daily Caller, several influential Senate Republicans voiced their doubts that Senate Minority Leader McConnell, R-Ky., was the best person to steer the party’s goals in the wake of the recent border bill fiasco.

“Mitch McConnell, in effect, gave the largest in-kind campaign contribution to the Democrats’ Senate campaign committee in history,” Sen. Ted Cruz, R-Texas, told The Daily Caller.

“Every single Democrat candidate in the country running for Senate, running for House will use the identical talking points — they will all say: We wanted to secure the border. We tried to secure the border, but the Republicans wouldn’t let us,” Cruz said. “Now, that is a wild-eyed lie. It is completely false. This bill would have made the border crisis worse.”
