I'm not a fan of Pres. Trump's many campaign-style rallies, either, but the writer is disingenuous to characterize Obama's perpetual campaigning thus:
But these rallies were attempts to grow public support for particular policies: Obama, Bush, and Clinton kept things focused on their agendas.
The agenda - that is, the latest proposed piece of legislative pandering posing as BHO policy - was just an excuse for campaigning.
