A View from the White House: Richard Wirthlin, President Reagan's pollster, takes seriously those recent polls that show Sen. John Glenn (D-Ohio) running stronger as a presidential candidate since his announcement April 21.

One danger to former vice president Walter F. Mondale, Wirthlin told reporters yesterday, would be an "early breakout" by Glenn that would "quickly erode" Mondale's major asset, his support from leaders of Democratic organizations. "The Democrats really want to win in 1984," he said, and could drop Mondale if he seemed to be fading.

He said Mondale has two liabilties: his connection with the Carter administration and the "Faustian decision" to take positions appealing to party constituencies in the primaries "that can make him seem the candidate of special interests in the general election." Glenn, he continued, carries "less baggage," but "also has to prove himself" and will be "blind-sided a couple of times between now and the end of the year" by unexpected issues or problems.

Glenn apparently is beginning to fear that he may be peaking too early. He reportedly told some Democrats that he is worried that his candidacy is moving too fast and he would like to slow it down a bit.
