They're catnip for commentators -- two dynasts announcing within two days. Except the differences far exceed the parallels -- one's a yellow-pad wonk related to a popular ex-POTUS who leads with 60 percent in Democratic polls. The other is a "Jar of Mayo" with 100 percent recognition yet only 10 percent in GOP polls. Lowry and Katrina debate why.

People who strive for power the way McConnell has done throughout his career cannot be trusted to "moderate" themselves.
