CLEVELAND Donald Trump may top the polls in the contest for the Republican presidential nomination, but this weeks debate was a reminder that the party has able rivals who eventually could take him down and who also could mount a stiff challenge to Hillary Rodham Clinton in the general election.

Trump performed in typical style Thursday in the two-hour debate the same style that has helped him blow past the other candidates. But as the campaigns broke camp here Friday morning, the smiles on the faces of other candidates advisers told the fuller story of what happened on the stage at the Quicken Loans Arena.

Everyone came out a winner or so the rivals advisers proclaimed. Some of that bravado was typical post-debate hype, but some of it was grounded in reality. Trump may have been the center of attention, but others performed more effectively overall.

For months, Republican leaders have talked about the breadth, depth and potential strength of their candidates. As a group, the aspiring nominees are certainly more experienced and seemingly more ready for a national campaign than the collection of politicians who sought to deny Mitt Romney the GOP nomination in 2012.

Democrats have enjoyed the summer of Trump and hope it lasts long enough to inflict serious damage on the Republican brand. But they no doubt saw enough Thursday night to begin to worry about what a general election pitting a vulnerable Clinton against one of the non-Trumps could portend.

On Thursday, a national television audience likely a record primary-debate audience got its first real look at candidates such as Sen. Marco Rubio of Florida, Ohio Gov. John Kasich, Wisconsin Gov. Scott Walker, Sen. Ted Cruz of Texas, New Jersey Gov. Chris Christie and Sen. Rand Paul of Kentucky. Even former Florida governor Jeb Bush probably isnt that well known, despite his familiar name.
