Political events exert different degrees of influence on supporters of different candidates. Sometimes a political event can cause a significant shift in support towards one candidate, but often, these events only sway a small fraction of voters — especially when supporters are loyal or have strong opinions. Factors that influence the impact of a political event can include the nature of the event, the media’s portrayal, the current political climate, and the demographic characteristics and pre-existing beliefs of the voters. For specific, up to date information on this particular poll and event, I recommend checking out reliable news outlets.
