Doyle McManus: Is Beto O'Rourke just another pretty face?
WASHINGTON - The most striking thing about the Democrats' newest presidential candidate is that he's so hard to pin down.
Even though Beto O'Rourke spent six years as a congressman from El Paso, he has offered few specific positions on issues. Instead, he mostly deploys sunny attitudes; he's for unity, bipartisanship and everyone pulling together.
"Let us not allow our differences to define us," he told voters in Iowa. He's a lanky, toothy Rorschach test; Democrats can project almost any view onto him they like.
That's unlikely to work long
