We shouldn't be surprised anymore.
There's apparently no depth too low for Donald Trump to sink in his unpresidented attacks on anyone who challenges him. And Rep. John Lewis, D-Ga., certainly did that, citing Russian interference in the election and questioning the legitimacy of Trump's presidency .
Even so, the president-elect's Twitter tirade against Lewis at the beginning of the Martin Luther King Jr. holiday weekend is still mind-boggling and a national embarrassment.
Trump called Lewis, who risked his life to defy segregation, who has been arrested 40 times for his unrelenting activism, who helped get voting rights for millions of Americans, who kept fighting even after his skull was fractured, "All talk, talk, talk - no action."
So let's compare Trump's actions to Lewis's actions.
We can start in 1960, when Trump was 14 and Lewis was 20. They both clearly showed their leadership potential early.
