"Great speech. She's tested. She's ready. She never quits. That's why Hillary should be our next @POTUS," Obama tweeted.
Clinton was nominated as the Democratic Party's presidential candidate earlier in the week.
She officially accepted the nomination on Thursday and will face Republican nominee Donald Trump in the national presidential elections on November 8.
While many have voiced reservations about both candidates, convention keeps many voters from selecting 'third party' candidates such as former Republican Governor of New Mexico Gary Johnson, who is running on the Libertarian Party ticket. Americans often don't so much love one candidate as much as they detest the other, and pick the "lesser of two evils" for fear of "throwing away" their votes.
Also running is Green Party candidate Jill Stein, who has attracted would-be Bernie Sanders voters who categorically reject Clinton for her dubious campaign tactics, acceptance of campaign funding from Wall Street, hawkish attitude towards military conflicts in the Middle East, and questionable stance on the Trans-Pacific Partnership, a secretive trade deal.
Both the individual liberty-oriented, anti-war Libertarians and the socialist-leaning, environmentalist anti-war Greens hope to capitalize on widespread animosity towards both Clinton and Trump.
