There’s definitely a difference in enthusiasm with the Republican’s benefiting this time. Other than the hardcore Demobots that pull the lever every election, many of the others will stay home and not vote for Biden.
The enthusiasm is entirely attributable to Trump.
Still he has a tough slog and is running in an environment where the Left has won the last two presidential elections without breaking a sweat.
He’s going to be under the microscope while Hillary will get a pass. That’s just the way things are.
In a word, to win in November, Trump is going to have to work harder than he’s ever worked in his entire life. We’ll see how much he really wants the job soon enough.
