During this period the Mexican underground political newspapers spread the new ironic slogan for the Porfirian times, based on the slogan ""Sufragio Efectivo, No Reelección"" (Effective suffrage, no re-election) and changed it to its opposite, ""Sufragio Efectivo No, Reelección"" (Effective suffrage – No. Re-election!). Díaz had the constitution amended, first to allow two terms in office, and then to remove all restrictions on re-election. With these changes in place, Díaz was re-elected four more times by implausibly high margins, and on some occasions claimed to have won with either unanimous or near-unanimous support.
