Challenge the lie that Mr. Obama killed Bin Laden.
Challenge the lie that Obamacare does not raise taxes on the middle class.
Challenge the lie that Federal welfare programs don't create dependency and weaken the family unit by substituting the Government for the husband.
Challenge the lie that the poor should have the option of not taking "jobs Americans won't do".
Challenge the lie that by executive order the President did not gut the work requirement for welfare.
The list could on and on.
