Keep in mind this is the second time in recent history they have pulled this vile Act of questioning the legitimacy of our president. Understanding leftist speak, that means they intend to install an illegitimate president.
Democrats have called for the impeachment of every Republican president since Richard Nixon. They are likely to continue to do so into the foreseeable future. They have also called every Republican presidential candidate dumb, senile, or both since Ronald Reagan. They are likely to continue to do so into the foreseeable future. They have also claimed each both close Republican winners, Bush and Trump, illegitimate, and are likely to do so into the foreseeable future.
